Fans of Dwayne "The Rock" Johnson have been watching him fight for years, dating back to his time in WWE, but this might be his biggest challenge yet. In a new motion poster for Johnson's movie "Hercules," he's squaring off with a gigantic lion.

Regardless of the size, is any lion truly problematic for the son of Zeus? "Hercules" also stars John Hurt, Ian McShane and Joseph Fiennes, and is directed by Brett Ratner. It hits theaters July 25.
